Statement I: To get a steady DC output from the pulsating voltage received from a full wave rectifier we can connect a capacitor across the output parallel to the load $R_L$.
Statement II: To get a steady DC output from the pulsating voltage received from a full wave rectifier we can connect an inductor in series with $R_L$.
In the light of the above statements, choose the most appropriate answer from the options given below:
Answer: (B) Both Statement I and Statement II are true
A capacitor in parallel with the load bypasses the AC ripple (capacitor filter), and an inductor in series with the load opposes changes in current (choke filter). Both smooth the output, so both statements are true.
